Wikipedia, Numerical approximations of π, 21st century – current claimed world record
In August 2009, a Japanese Supercomputer called the T2K Open Supercomputer was claimed to have more than doubled the previous record by calculating π to 2,576,980,377,524 digits in approximately 73 hours and 36 minutes.
In December 2009 Fabrice Bellard used a home-computer to compute 2,699,999,990,000 decimal digits of π. The base-2 calculation, conversion to base 10 and verification took 131 days.

Pi Computation Record
PC used during the computation:
* Core i7 CPU at 2.93 GHz
* 6 GiB (1) of RAM
* 7.5 TB of disk storage using five 1.5 TB hard disks (Seagate Barracuda 7200.11 model)
Backups were done using 2 TB hard disks (Seagate Barracuda LP model).
The verification of the binary digits used a network of 9 Desktop PCs during 34 hours. It could have been done on the same PC as the main computation by using 13 more days.

Inače, autor programa je takođe autor za sada najbrže formule za izdvajanje pojedinačnih binarnih cifara broja
bez računanja prethodnih cifara.Ako ovo nije za Tjuringovu nagradu, ne znam šta je.
Nije bitno koji su zaključci izvučeni, već kako se do njih došlo.
